摘要
研究了磁黄铁矿和脆硫锑铅矿在捕收剂存在时的浮选行为 ,发现二者在pH =2~ 12的范围内均有良好的可浮性。选用工业常用调整剂石灰进行了选择性分离浮选试验。结果表明 ,石灰不能很好地分离脆硫锑铅矿和磁黄铁矿。通过红外光谱分析测定了矿物表面与药剂的吸附产物 。
The flotation behaviors of jamesonite and pyrrhotite in the presence of collector was investigated. It was found that both of them have a better flotability at pH=2~12. The flotation separation of jamesonite from pyrrohite was made by using calcium oxide as regulator. The results showed that calcium oxide could not make both of them separate from each other very much. Absorbed products between the minerals surfaces and the reagents were measured by infraed spectrographic analysis.
